AXLE.

Specification of Letters Patent.

.atented June 5, 1906.

T at whom it may concern.-

Be it known that we, SHERMAN H. NICK- ERSON and ALVINZA V. NIOKERSON, citizens of the United States, residing at Canton, in the county of St. Lawrence and State of New York, have invented new and useful Improvements in Axles, of which the following is a specification.

Our invention relates to improvements in axles, and has for its object certain novel features of construction hereinafter described and claimed.

The invention consists in fitting the. axlespindle with bearing-sleeves, which are so constructed that the axle will not be weakened by their use and one of which sleeves can also be adjusted to take up wear.

In the accompanying drawings, FigurFe 1 is 1g. 2 is a longitudinal section on the line 2 2 of Fig. 1.

Referring specifically to the drawings, 5 indicates the spindle of the axle 6. The outer end of the spindle has the usual threaded stem 7 to receive the axle-nut and at the inner end has a shoulder 8. In front of this shoulder the spindle is enlarged, as at 9, which adds to the strength of the spindle and lessens the liability of fracture, which usually takes place at this point.

The inner end of the spindle is threaded, as at 10, to receive a bearing-sleeve 11., having at one end a flange 12, which when the sleeve is in position abuts against the shoulder 8 and forms the butting-ring for the Wheelhub. The threads 10 do not extend up to the shoulder 8, so that the portion of the spindle most susceptible to fracture is not weakened. The bore of the sleeve fitting on that portion of the spindle which is not threaded is also without threads and is shaped to fit snugly on the enlargement 9.

The outer end of the spindle is threaded, as at 13, to receive a second bearing-sleeve 14, which is made longer than the threaded portion 13 and extends beyond the outer end of the spindle. This construction permits the sleeve to be adjusted lengthwise on the spindle to take up end wear. In the under side of the spindle, between the sleeves, a lubricant-recess 15 is made in which a suitable lubricant-retainer 16 can be placed.

An axle constructed as herein described will be strong and durable and can be readily repaired, as the bearing-sleeves are removable and can be replaced when worn. Wear of the flange 12 is readily taken up by screwing the sleeve 14 farther in.

Having thus described our invention, what is claimed as new, and desired to be secured by Letters Patent, is

An axle-spindle having a shoulder at its inner end and enlarged in front of said shoulder, said spindle being threaded and the threads ending at a distancefrom the enlargement, and a bearing-sleeve screwed on the threaded portion of the spindle and extending over the said enlargement, and having a flange abutting against the aforesaid shoulder.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
